[ARC5] Transformers in low-voltage to B+ supplies

[Leslie Smith]

Hello all:

I wish to build a lead-acid battery to B+ inverter using (probably) a
conventional iron-core transformer.  Two configurations are generally seen
in typical circuits.  I will describe these as "H" bridge and solid-state
vibrator replacement.  The "H" bridge uses an untapped low-voltage winding;
the vibrator circuits use a transformer with a center-tapped primary
winding.

Since I can choose the switching frequency, and a higher frequency has some
advantages, what limits the operating frequency?  Assume a conventional EI
(or perhaps toroidal) core using common transformer iron.  (I assume the
'iron' used in most power transformer share a 'common' quality.)

I intend to feed 'the beast' with a trapezoidal wave-form not a sharp
square wave.

Thanks for observations.

Leslie
